by far the largest species, HaploIopJms being the only other which ap- 

 proaches it in this respect. The emargination of the clypeus, very 

 deep in the male but feeble in the female, is apparently a unique char- 

 acter in the family, and the antennae are peculiarly thick and compact 

 in the male, though bearing some resemblance to those of Eiuphylus ; 

 the female antenn;i3 are much shorter, more slender and with relatively 

 larger club. The eyes are almost without parallel in the family in 

 their position upon the side of the head and in their relatively slight 

 convexity, the convexity and prominence of these organs being one of 

 the most characteristic features of the family. The body is oblong, 

 rather convex, very finely, densely punctate and clothed, often densely, 

 with very short subappressed pubescence. The elytra in some of the 

 paler forms clearly show the regular series of areolae on their under 

 surface, shining through the diaphanous chitin and perhaps of signifi- 

 cance in indicating that the family may be derived from seriately 

 punctate archetypes ; at present these series of areolae are not con- 

 nected in any way with the punctuation of the surface, which is alto- 

 gether irregular, but there are frequently very feebly impressed super- 

 ficial lines which appear on the exposed surface above them. The 

 species are few in number and those in my cabinet may be thus char- 

 acterized : — 



Body large, more liroadly oblong, densely clothed with pubescence which nearly con- 

 ceals the surface, the eyes smaller, the mandibles more prominent ; tibia- rapidly 

 enlarged from base to apex ; basal angles ot the prothorax more or less obtuse... 2 



Body smaller, the sides of the protliorax parallel and straight, the basal angles right 

 and not at all blunt; body smaller, the eyes moderately large, rather more convex 

 and less finely faceted, the mandibles smaller and less prominent, the pubescence 

 quite sparse, not at all concealing the surface ; tibiae but feebly enlarged from 

 base to apex ^ 



2 — Body broadly oblong, testaceous throughout, the antennse of the male except at 

 base and apex, and the tibiae toward base, blackish ; antennae of the male thick, 

 almost as long as the head and prothorax, the second joint much shorter than the 

 third though equal in width ; prothorax distinctly less than twice as wide as long, 

 parallel and almost straight at the sides, but slightly rounding and convergent at 

 apex and base, the punctures fine and dense ; elytra not wider than the prothorax, 

 a third longer than wide, obtuse at apex, very densely and finely punctate. 

 Length 4.1-4.5 mm.; width 1. 7-1. 9 mm. New York to Minnesota. 



ochraceus MchJi. 



Body less broadly oblong and slightly smaller, equally densely but still more minutely 

 punctate and densely clothed with short cinereous pubescence, pale tlavo-testa- 

 ceous, the tibiae and antennas colored as in oc/iracens, the latter thick in the male 

 and much shorter than the head and prothorax, the second joint equal in length
